/** 
 *  This is an example of using the SnmpTable class.
 *  This is a command line application that does not require JFC/swing
 *  components.This can be used to get a single row from a table if
 *  the index of that row is known.  
 *
 * [-d]                   - Debug output. By default off.
 * [-c] <community>       - community String. By default "public".
 * [-p] <port>            - remote port no. By default 161.
 * [-t] <Timeout>         - Timeout. By default 5000ms.
 * [-r] <Retries>         - Retries. By default 0.      
 *<img SRC="images/v3only.jpg" ALT="v3 only"> [-v] <version>         - version(v1 / v2 / v3). By default v1.
 * [-u] <username>        - The v3 principal/userName
 * [-a] <autProtocol>     - The authProtocol(MD5/SHA). Mandatory if authPassword is specified
 * [-w] <authPassword>    - The authentication password.
 * [-s] <privPassword>    - The privacy protocol password. Must be accompanied with auth password and authProtocol fields.
 * [-n] <contextName>     - The snmpv3 contextName to be used.
 * [-i] <contextID>       - The snmpv3 contextID to be used.
 * host Mandatory         - The RemoteHost (agent).Format (string without double qoutes/IpAddress).
 * tableOID  Mandatory    - Give the Object Identifier of a Table.
 * mibs  Mandatory 	      - The mibs to be loaded.Mandatory.
 * rowIndex  Mandatory    - Index of the row .
